sarcosinate :-)
Hi all,
so a discussion on another thread made me want to revisit the issue of formulating a sulphate free shampoo based on commonly available surfactants locally. I used the following:
sodium lauroyl sarcosinate 24%CAPB 8% - so to stay in the 1:3 surfactant holy grail
Lauryl glucoside 5% / and or disodium cocoamphodiacetate
get an ASM of slightly over 11
for foam boosting i used CDE 1% - no cmea available without import from BASF
thickening PEG-150 disterate 1%
some peg-7 glyceral cocoate 1% - slightly cheaper than the lamesoft po65 i have in the labpoly quat 7 -1% 1 % glycerine
1% euxyl PE 9010
0.3 % fragrance
some citric for ph
0.1 of a chelating agentso the foam is not to great and i struggle to thicken it properly without using a polymer or a gum. i have tried ethylene/sodium acrylate copolymer on the second batch but was not to impressed with the added thickness its supposed to give me
any suggestions on how to make this better? -

Decyl Glucoside is a great foam booster (it thins out the product though). I think you can up % PEG-150 Distearate to 1.5%

get rid of PEG-150 distearate and use a high-viscosity grade of hydroxypropyl methylcellulose (Methocel) instead; in addition to the the thickening effect, it also boosts the foaming of surfactant-based products
